LexiDeck 莱西词卡
Terms of Use
Last updated and effective: September 7, 2026
1. Agreement and scope
These terms apply to your use of LexiDeck (莱西词卡) and related services, provided by the entity that develops the app (“we”). Please read these terms before use. If you disagree, do not use the relevant services. Platform-specific terms apply only to the corresponding version.
2. Learning services
LexiDeck offers vocabulary card matching and sorting, learning levels, practice, mistake review, dictionary lookup and pronunciation, daily tasks, XP, badges, statistics, weekly themes and leaderboards where available. Content and availability vary by version and platform. LexiDeck is a learning aid; it does not guarantee exam results, vocabulary mastery or uninterrupted content updates, and is not affiliated with examination bodies merely because a deck refers to an exam.
3. Eligibility and account security
You must have legal capacity to accept these terms. Minors should use the service with a parent or guardian's guidance and obtain any consent required by local law, including for purchases. A store age rating does not replace that consent. Keep your device and Apple or HUAWEI account secure, use only accounts you are authorized to use, and contact us if you suspect unauthorized activity.
4. License and intellectual property
Subject to these terms and applicable store rules, you may use LexiDeck for personal, non-commercial learning on devices you own or control. The app, decks, artwork and other content remain owned by us or their licensors. Do not resell, redistribute, bulk extract, bypass purchase verification, interfere with services or reverse engineer the app except where applicable law permits. Third-party dictionaries, software and resources retain their own licenses and notices.
6. Subscriptions and automatic renewal
Once you confirm a subscription, the payment platform will charge and renew it for your chosen period until cancellation. Prices and offer conditions are explained at purchase. Use the purchasing platform to manage your subscription, check renewal details or cancel. Failed payments may interrupt paid access.
iOS · App Store
Apple handles payment and renewal for subscriptions purchased through the App Store. Subscriptions renew for the confirmed period unless canceled before renewal. Billing arrangements and any notices provided by Apple follow its applicable service rules and purchase confirmation. Cancel using Apple’s subscription-management features; see Apple’s official guidance. For a free or discounted trial, follow Apple’s guidance to cancel at least 24 hours before it ends to avoid renewal.
HarmonyOS · Automatic Renewal Service Agreement
Huawei handles payment and renewal for subscriptions purchased through Huawei In-App Purchases. You can also choose a one-time purchase without automatic renewal. A subscription requires your agreement and payment confirmation. If a free or low-price trial is offered, your consent will be obtained after it ends before starting automatic renewal.
On HarmonyOS 5.0 and later, Huawei In-App Purchases provides a system notification 5 days before charging to remind you of renewal. How you view the notice depends on the features provided by the platform.
You can cancel before the new period starts through Huawei or your payment provider; see cancellation help. Contact us if you need assistance. If you request account deletion with an uncanceled subscription, we will remind you to address it.
7. Cancellation and lifetime access
Canceling renewal normally leaves paid access available until the end of the purchased period; trial access may end earlier under platform rules. Uninstalling the app, resetting progress or requesting data deletion does not cancel a subscription. A lifetime purchase is a one-time, non-renewing Premium unlock tied to the purchasing account, with no subscription expiry. Buying lifetime access does not automatically cancel an existing monthly or yearly subscription. Cancel it separately to avoid further renewal charges. Supported devices and operating system versions may change as the app is updated. A one-time purchase does not guarantee that later app versions will always remain compatible with the device or operating system used at purchase. These changes do not affect your statutory rights.
8. Restore purchases and refunds
Use Restore Purchases where available with the original purchasing account to recover eligible entitlements. Purchases and learning data do not automatically transfer between Apple and Huawei accounts or platforms unless expressly supported. For Apple purchases, request a refund through Apple's refund service. For Huawei purchases, use the relevant order support or contact us with order details, never passwords or full payment credentials. Eligibility is governed by applicable consumer law and platform procedures; these terms do not impose a blanket no-refund rule. A refunded or revoked purchase may lose its corresponding entitlement.
9. Profiles, leaderboards and fair play
Display names, composed avatars and eligible scores may be visible to other users when public features are used. Do not impersonate others, infringe rights, publish unlawful, abusive or discriminatory names, cheat, fabricate scores or misuse promotions or invitation codes. We may moderate names, remove invalid scores and proportionately restrict abusive activity. Report concerns or appeal a decision by email below. You retain rights in submitted content and permit only its hosting, moderation and display needed to operate these features. XP, badges and rankings are learning records, have no cash value and cannot be redeemed for money.
10. Progress, synchronization and reset
Progress is stored on your device. iOS may synchronize it through iCloud when enabled; HarmonyOS cloud synchronization depends on supported services and your authorization. Connectivity, account settings and conflicts can delay synchronization. Read the in-app warning before resetting data: unsynchronized or reset progress may be unrecoverable. Do not assume resetting learning data also deletes server profiles, leaderboard records or store purchases; contact us for server-data requests.
11. Privacy and permissions
Our Privacy Policy explains learning data, platform identity, public profiles, display-name moderation and diagnostics. Accepting these terms does not replace any separate privacy consent or permission required by law. You may use available system and in-app controls and contact us to exercise applicable data rights.
12. Changes, suspension and ending service
A one-time purchase does not guarantee that online services will operate indefinitely. We may correct content, maintain services and update features. For material changes to these terms or paid services, we will give reasonable advance notice in the app or through another suitable channel and seek renewed consent where required. Changes do not retroactively remove accrued consumer rights. Serious abuse or security threats may require immediate, proportionate restrictions; you may contact us to appeal. If we discontinue a paid service or materially cannot supply it, we will provide notice and any refund or other remedy required by law. You may stop using the service at any time, managing subscriptions separately.
13. Platform terms and consumer rights
For App Store downloads, the Apple Standard End User License Agreement governs the software license; these terms supplement it for LexiDeck services and do not replace it. Huawei account, AppGallery and payment terms apply to their respective services on HarmonyOS. LexiDeck support and service complaints should be directed to us, not treated as a promise by Apple or Huawei. Nothing here excludes mandatory warranties, refunds, liability or other consumer protections, including liability that cannot legally be excluded. Applicable mandatory law prevails; disputes may be brought before a court competent under that law. Translations are provided for accessibility without reducing local consumer rights; report inconsistencies to us.
14. Contact
For support, billing help, complaints, appeals or data requests, email jeff@coolmind-innovations.com. Include the app version, platform and relevant order reference where useful. Do not send account passwords or full payment-card details.
